PALO PINTO COUNTY – Palo Pinto Academy opened on the 15th of October with 70 pupils, and has now about 100. B. F. Weaver succeeds D. P. Deaver, deceased, as Principal. The prospects for the tone of future instructions is flattering in the county. Out of 22 certificates issued, about half are first grade, and only one third grade. There are 38 communities in the county, and but 22 as yet have teachers. The teachers are thinking of organizing an institute soon, and one of the first things to be considered is the establishment of a teachers’ library. It is believed that a library will help to avoid the rock (want of interest) upon which many county institutes split.

Maybe Mr. Weaver used Andrews' Lunar Tellurian to instruct his pupils. As shown in the diagram: A. The globe ball. S. Arc of the sun's circumference, drawn upon the same scale as the globe. Extend the arc S until a circle is completed, and this circle shows the size of sun upon the same scale as the globe represents the earth. B. The circle of illumination, showing how far the sunlight extends. C. The twilight circle showing how far the twilight extends. D. The moon ball, showing the light and dark hemispheres of the moon. The gearing at F keeps the light hemisphere always toward the sun. E. Plate showing the inclination of the moon's orbit. G. A calendar index. L. Pointer showing the position of the sun's vertical ray. H. A longitudinal or time index, used to find time of sunrise and sunset, length of days, nights and twilight. J. The ecliptic. K. The equator.
